Named parameters, like in VBA?
Not listed get default values.
If position accept list, like list of pages, let it be string "1-5, 7, 9".
Or just one big string with named parameters list inside
("pages = 1-5, 7, 9 ; orientation = landscape; leftMargin = 1.5 cm")

So, for consistency with other LB printer settings, you are proposing something like:
Code:PrinterSetup$ = "orientation = landscape; leftMargin = 1.5 cm"

well, kind of.
May be - for consistency with LB GUI commands - get rid of "=", so it becames
Code:PrinterSetup$ = "orientation landscape; leftMargin 1.5 cm"
?

I think I'd be inclined to simplify even further:
Code: PrinterName$ = "DoPDF v7"
PrinterFont$ = "Arial 12 bold"
PrinterColor$ = "blue"
PrinterSetup$ = "landscape 15 10 10 10"
I should add that at present I have no plans for a new release of LBB but I'll make a mental note of the possibility of such additions should the atmosphere change.
Richard.

Code:
PrinterName$ = "DoPDF v7"
PrinterFont$ = "Arial 12 bold"
PrinterColor$ = "blue"
PrinterSetup$ = "landscape 15 10 10 10"
Doesn't it look like too many reserved words?

What problems do you see, and what is the alternative? Combining PrinterColor$ and PrinterSetup$ in a single new command seems to me illogical and inconsistent with the rest of LB, and the compatibility issues arising from having both are minimal.

I see single entity - printer - and several keywords associated with it
PrinterName$
PrinterFont$
PrinterColor$
PrinterSetup$
Suppose you will want to add two side printing or DPI setting or paper size - will you add still another word?
I think pack it all in single string is better, much like OPEN COM from LBB helpfile:
Code:open "COMn: [baud=b] [parity=p] [data=d] [stop=s]
[to=on|off] [xon=on|off] [odsr=on|off] [octs=on|off]
[dtr=on|off|hs] [rts=on|off|hs|tg] [idsr=on|off]"

Of course not - those are setup features which would be set using PrinterSetup$.

Mixing things which can only be changed before you print (e.g. page layout) with things that can be changed within a page (e.g. font and colour) is wrong in my opinion. But since we disagree to such a great extent it is probably better if I forget this feature altogether.

Ok I admit I never thought of this from this point.
You are right.

No-no-no.
You are the boss. You asked for suggestions - here we are - but decision is yours.
And feature implemented in different way is much better then feature non-inplemented, IMHO.

Richard....your suggestion is good, please do consider if there is future enhancement. 
btw...another question on this printing....if the output goes more than 2 pages, is there a way for us to put a header for each page? and also page number?

I think I have a program which does that, but unfortunately it's on my PC at home and I don't have access to it where I am. Remind me in a couple of weeks.

Here is the program. It's intended as a proof-of-principle, in practice you would probably want to put the printing code in a SUB so it can be called from multiple places:
Code: PrinterName$ = "DoPDF v7"
pv = 99999
page = 1
for i = 1 to 200
oldpv = pv
!pv = @vdu%!-8
if pv < oldpv then
lprint "THIS IS THE HEADER FOR PAGE "; page
lprint
page = page + 1
end if
lprint "This is line "; i; " of text sent to the printer"
next
dump
Note that this can't work if you are relying on the 'word wrap' capability of LPRINT (unless you output each word individually), because if it wraps from one page to the next it's impossible to print the header part way through the output string.
Richard.
